[. . . ] These power handling ratings are achieved using a 6 dB crest factor which provides peak levels 4 times that above the continuous rating of 350-watts. The Eliminator Monitor also features a stand mount adapter on the woofer side for vertical orientation (standard 1 3/8 diameter. ) Speaker Protection The Eliminator Monitor, like all other vented systems, experiences rapidly increasing cone excursion below the boxtuning frequency, while the acoustic output decreases rapidly. Therefore, to protect the Eliminator Monitor and maximize the power output of the system, it is necessary to insert an active 45- to 80-Hz highpass filter into the circuit. The filter should have a slope of at least 12 dB per octave. [. . . ] The densely woven, industrial-grade, abuse-resistant carpeting provides a finish that is both attractive and highly durable. Heavy-duty corner protectors, firmly secured rubber feet, recessed handles and a protective metal grille complete the picture and ensure that the Eliminator Monitor speaker system is ideally suited to a long and reliable life on the road. Frequency Response The combination of a 15-inch woofer, widebandwidth high-frequency driver and an equalized crossover results in the wide and smooth overall response shown in Figure 1. This response was measured at 3. 05 meters (10 feet), using a 4-volt swept sine-wave input in an anechoic chamber. Figure 1 has been averaged and corrected for 1 watt at 1 meter. Connections The Eliminator monitor is equipped with two parallel 1/4-inch phone jacks. (The Eliminator Monitor E version has two parallel Neutrik Speakon® NL4MP connectors. ) Another system can be connected in parallel by using the other connector. Care must be taken not to abuse the amplifier by connecting impedances which are too low. Constant-Directivity Speaker System The crossover frequency and speaker component geometries have been selected so that the directional characteristics of the woofer and constant-directivity horn match at the crossover frequency to create a special system type the constant-directivity system. At higher frequencies the vertical coverage pattern remains constant and the horizontal pattern smoothly transitions to a 55° angle above 5, 000 Hz. Response within the 80° x 55° rated coverage angle is uniform, which means 2 dependable coverage without hot spots or dead zones at certain frequencies. Larger amplifier ratings are recommended for maximum dynamic range, but it should be recommended that amplifier continuous levels (as opposed to peak levels) be within the range quoted for the Eliminator® Monitor long-term average power-handling rating. Service In the unlikely event the Eliminator Monitor requires service, the woofer and driver can both be replaced or serviced from the front. A service data sheet is available from Electro-Voice.
